Ubuntu

Packages for the MSP430 toolchain are available in the Ubuntu repositories. To fetch the required packages, run:

sudo apt-get install build-essential srecord binutils-msp430 gcc-msp430
gdb-msp430 msp430-libc msp430mcu mspdebug dos2unix

This will install the build toolchain and the mspdebug tool.

Writing and Building Firmware

1. Clone the msp430-template repository (or fork it and clone your own repository).

    git clone [email protected]:uctools/msp430-template
   

2. Modify the Makefile:

   • Set TARGET to the desired name of the output file (eg: TARGET = main)
   • Set SOURCES to a list of your sources (eg: SOURCES = main.c two.c three.c)
   • Set MCU to the MSP430 part number to build for (eg: MCU = msp430g2231)

3. Run make

4. The output files will be created in the 'build' folder

Flashing

mspdebug

To flash a device using mspdebug, run mspdebug and specify a debugger. For the MSP430 Launchpad, the debugger is rf2500:

mspdebug rf2500

Note, you may need to run mspdebug as root.

In mspdebug, you can load and run the program:

(mspdebug) load build/main.hex
(mspdebug) run

Further support on using mspdebug is available on the mspdebug homepage and in the mspdebug manual.
